TTE

TerminalTextEffects is a collection of visual effects that run inline in the terminal. The underlying visual effect framework supports the following:

• Xterm 256 color and RBG hex color support
• Color gradients
• Runs inline, preserving terminal state and workflow
• Dynamic character movement with motion easing
• Dynamic animations with symbol and color changes
• Effect customization through command line arguments

Requirements

TerminalTextEffects is written in Python and does not require any 3rd party modules. Terminal interactions use standard ANSI terminal sequences and should work in most modern terminals.

Note: Windows Terminal performance is slow for some effects.

Installation

pip install terminaltexteffects

Usage

cat your_text | tte <effect> [options]

OR

cat your_text | python -m terminaltexteffects <effect> [options]

• All effects support adjustable animation speed using the -a option.
• Use <effect> -h to view options for a specific effect, such as color or movement direction.
  • Ex: tte decrypt -h
